SCIaims.

I'his invention relates .to cooking stoves and the like.

One object of the invention is the provision, in the oven or similar cooking compartment of a stove, of a rack operating bar adapted for engagement with the rear portion of the pan supporting rack or racks, the bar having an extension pivotally supported on a wall of the cooking compartment and being adapted for external operation So as to move the racks inwardly or outwardly on their supporting guides.

Another object of the invention is the provision of a rack operating means having .provision for automatically disconnecting the same from the rack at the end of the returning movement of the operating means, to permit free withdrawal of the rack.

Other objects and advantages of the invention will be apparent from the following description,

the appended claims and the accompanying drawings, in which,.

Fig. 1 is a top plan view of a cooking stove em- 35 reference numerals, I0 designates generally a cooking stove having anoven II, provided with the usual gas or electric heating means which has not been illustrated as such heating means may be of any desirable form. The oven is de- 40 fined by the side walls I2 including the vertical walls and top and bottom, the front of the oven compartment being closed by the door I3 which is hinged in any suitable manner so as to open outwardly to expose the front of the oven. On 45 the laterally opposed vertical side walls I2 of the oven are rack supporting plates l 4 which are provided with ribs or ridges along which the pan supporting racks or grids I5 are mounted for sliding movement. Each grid or rack l5 may be 50 mounted at any desired height in the oven as it can be readily withdrawn and reinserted on 'a different pair of ridges of the plates I4. The side bars of the racks, adjacent their rear ends, are humped upwardly as at I6 to prevent any large 55 amount of vertical play between the guide ridges.

In the usual form of stove construction it has been necessary to grasp the pan supporting racks in order to pull them part way out of the oven so as to expose the top of the pan or pans supported bythem in order to ascertain whether or 5 y not the contents of the pans have been suiliciently cooked, or for basting or other reasons. Since the `racks arevery h'ot this has resulted in frequent burns to the hands, and has required a person to use a heat insulating pad o f some sort 10 in moving the racks either .partly from or back into the oven. In accordance with the present invention, however, a means is provided externally of the stove which can be readily manipulated by the hand without danger of burns and 15 which is adapted to move the racks regardless of their height location, this means being of a simple and inexpensive character, and of such character as to permit the racks to be pulled all the way out ofthe oven from their normal housed posi- 20 tions, whenever desired.

Referring to the form of construction illustrated in Figs. 1 to 3 inclusive, in which the invention is applied to a table top type of stove, the rack moving mechanism comprises a vertical bar I'I which extends downwardly along the rear wall of the oven when in its normal position as shown in Fig. 2, a sleeve member I8 being preferably carried by the bar for rotatable movement thereon. The upper end of the bar has an exv ytension t9 which is rotatably mounted in' a suitable bracket 20 provided on one of the walls of the oven at a substantial horizontal distance from the bar I1. The har I'I is thus adapted for swinging movement in an are of a circle, and when moved forwardly toward the front of the oven it pushes upon the rear side 2| of the rack I5 and thus nieves the rack forwardly from its normal housed position.

The extension I9 is operated by means of a 40 horizontal shaft 23, to which it is operatively coupled as by means of beveled pinions 24 and 25. The shaft 23 projects from the oven wall, its outer end being xed to a hand lever 2S which can be swung forwardly toward the operator so as to move the bar I'I forwardly and effect outward movement of the pan supporting rack or racks. The rack I5 can thus be moved to an extended position illustrated in Fig. 1, in which about one-third of the rack is still retained within the oven and guided on the ribs of the supporting plates I4.l y The bar I1. is adapted to retract the racks as well as to advance them, and in order that rearward movement of the bar I1 will retract the 55 racks, each rack is provided rigidly with a hook shaped member. 2l preferably arranged about midway between the sides of the oven. 'Ihe end 29 .of this hookmember does not extend far 5 enough toward the bar I1 to reach behind the bar when the latter yis in its fully retracted position, so that when the bar is in such position, illustrated in Fig. 2, the-racks are entirely disconnected from the bar and may-be grasped by the hand and pulled all the way from the oven in order td be reinserted at a different height;

However, as soon as the bar. is moved forwardly' it swings toward the left as viewed in Fig. 2 .thus comes in front of the end 2 2of the hook.' l

and remains in front of the hook throughout the normal forward swinging movement' of the bar and can, therefore, move the rack back into the oven when desired. It will be noted that the final returning movement of the lever 2| automatical1y disconnects the rack vfrom the connecting means to permit free withdrawal of the rackwhile the connecting means and its oper ating hand lever remain stationary.

Stop means are provided.in order to'limit the forward travel of the bar I'I to such position as to maintain the bar in front of the end 2| of .the hook so that normally the racks cannot be moved by the bar to such an extended position as to be inadequately supported by the ribs of the supporting plates Il. For this purpose, the side of the stove is shown as having metal straps 30 and 3| suitably spaced to provides recess 32 in which the lever 26 is retained when the bar is in its fully retracted position. The lever, how- 5 ever, is sufilciently iiexible so that its guided portion may be deflected toward the right and thus moved out of the recess 32 and the levex` can then be moved forwardly in the slot $3 until it engages the stop 3l, which limits the forward 0 movement of the bar to such position that the rack is not moved more than about two-thirds oi' its length out of the oven. If desired, -provision may be made for movingthe bar still fur-` ther imorder to -again clear the bar I1 from the 45 hook 28, as shown in the position illustrated in dotted lines in Fig. 1, the lever 2l under such circumstances having been sprung further tothe right and then moved into the slot 35. Inasmuch as the rack hook is entirely freed from the 50 bar I1 when the ylatter is in its fully retracted position, however, it is not always necessary to p rovide for the release of the rack from the bar when the bar is in its extreme forward position.

It will be apparent that the operation of the '55 racks is independent of the operation of the door I3, and itrwill also now be apparent that the operation of (the racks can be effected in a very convenient manner and by means ofA a very simple construction embodying only a very'few mov- `60 ing parts. y

Figs. 4 and 5 'show a modified form of construction which may be used, for example, on a stove inwhich the top'of the oven is arranged f some distance above the cooking top. In this 55 form of construction the operating lever 31 is shown on the top of the oven 3l. The lever I1 is connected to the upper end of an extension 39 of the bar 40, the extension 39 being rotatably mounted for movementE about a vertical axis in 70. the upper wall of the oven on a bearing sleeve Il. A stop member M is preferably provided to positively limit forward swinging movement of the bar to a position corresponding to a rack Losition in which the rack is about two-.thirds ex- 75 tended from the oven. The cooperation between the bar lll and-the racks Il and 42 andthemanner in which the racks are mounted on the oven side. walls is similar to the form of construction previously described. A

While the formsof apparatus herein described constitute preferred embodiments of the invention, it is tolbe understood that the invention is not limitedto these precise forms of apparatus, and that changes may be made therein without departing from the scope of the invention w is defined in. the `appended claims.
